Description

Die Erfindung bezieht sich auf ein Langhaarscherteil, inbesondere für Trockenrasierapparate, mit einem am Scherkopf angeordneten Scherkamm und einer hin- und herbewegbaren, gezahnten Scherklinge, welche von einer am Scherkopfrahmen abgestützten Abdrückfeder in Anlage an den Scherkamm gehalten ist.The invention relates to a long-hair shear part, in particular for dry shavers, with a shaving comb arranged on the shaving head and a reciprocating, toothed shaving blade which is held in abutment with the shaving comb by a push-off spring supported on the shaving head frame.

Ein solches Langhaarscherteil ist z. B. in der DE-OS 20 19 978 beschrieben. Ein generelles Problem von Langhaarscherteilen besteht darin, daß ihre beiden Schneidelemente, der Scherkamm und die Scherklinge, über ihre ganze Länge einwandfrei unter möglichst gleichmä-βigem Anpreßdruck aneinanderliegen müssen, ohne daß dadurch das Larghaarscherteil zu schwergängig wird.Such a long hair part is z. B. described in DE-OS 20 19 978. A general problem of long-hair shear parts is that their two cutting elements, the shaving comb and the shaving blade, have to lie perfectly against one another over their entire length, with the contact pressure being as uniform as possible, without the larg hair shear part becoming too stiff.

Bei dem in der DE-OS 20 19 978 beschriebenen Langhaarscherteil liege die Scherklinge auf der ihrer Verzahnung gegenüberliegenden Seite nur mit einem Ansatz oder mit mehreren Ansätzen gegen den Scherkamm an. Dadurch ist die Gefahr eines Verziehens der Scherklinge beim Schleifen geringer, weil keine lange, durchgehende Fläche geschlif-fen werden muß.In the long-hair shear part described in DE-OS 20 19 978, the shaving blade lies on the side opposite its toothing with only one attachment or with multiple attachments against the shaving comb. Thereby the risk of distortion of the lower shearing blade during grinding, because no long continuous surface must be closed i f-fen.

Um geringe Reibkräfte zu erhalten, lehrt die DE-OS 20 19 978 des weiteren, zwischen der Andrückfeder und der Scherklinge eine Gleitleiste vorzusehen. Trotzdem erhält man jedoch immer noch beträchtliche Reibkräfte, die unangenehmerweise durch Fertigungstoleranzen bei den Bauteilen des Langhaarscherteiles stark schwanken. Deshalb empfiehlt die DE-OS 20 19 978, das Langhaarscherteil als Baueinheit so zu gestalten, daß seine Funktion überprüft werden kann, bevor das Langhaarscherteil am Trockenrasierapparat angeschraubt wird.In order to obtain low frictional forces, DE-OS 20 19 978 further teaches to provide a slide bar between the pressure spring and the shear blade. Nevertheless, considerable frictional forces are still obtained which fluctuate uncomfortably due to manufacturing tolerances in the components of the long-hair shear part. That's why DE-OS 20 19 978 recommends designing the long-hair shear part as a unit so that its function can be checked before the long-hair shear part is screwed onto the dry shaver.

Der Erfindung liegt die Aufgabe zugrunde, ein Langhaarscherteil der eingangs genannten Art zu entwickeln, welches einfach in der Herstellung ist, dessen Reibkräfte jedoch mit möglichst geringen Antriebskräften überwunden werden können.The invention has for its object to develop a long-hair shearing part of the aforementioned type which is simple to manufacture, the frictional forces can be overcome, however, with the lowest possible ntriebskräften A.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen der Andrückfeder und der Scherklinge mindestens ein Andrückhebel angeordnet ist, welcher an der Scherklinge und dem Scherkopfrah- men abgestützt ist und gegen den die Andrückfeder anliegt.This object is inventively achieved in that a pressing lever is disposed between the pressure spring and the shearing blade at least that of the shear blade and the Scherkopfrah- is supported men and abuts against the pressure spring.

Durch die erfindungsgemäße Anordnung eines Andrückhebels kann die Kraft der Andrückfedern so umgelenkt werden, daß sie in Bezug auf die Funktion des Langhaarscherteiles in optimaler Position und Richtung in die Scherklinge eingeleitet wird. Die Andrückfedern können z. B. im Scherkopfrahmen des Trockenrasierapparates angeord- net sein und bei einem schräg dazu angeordneten Langhaarscherteil sich derart am Andrückhebel abstützen, daß die Kraft der Andrückfe- dern rechtwinklig in den vorderen Teil der Scherklinge des Langhaarscherteils eingeleitet wird.Due to the arrangement of a pressure lever according to the invention, the force of the pressure springs can be deflected in such a way that it is introduced into the shaving blade in an optimal position and direction with regard to the function of the long-hair shear part. The pressure springs can e.g. Be as in the shaving head frame of the dry shaving angeord- ne t and such support in an obliquely disposed to long-hair shear section at the pressing lever, that the force of Andrückfe- de rn right angles is introduced into the front portion of the shear blade of the long-hair shearing part.

Diese Andrückkräfte werden, wie gesagt, dort in die Scherklinge geleitet, wo es für die Funktion des Langhaarscherteiles richtig ist, also möglichst nahe der Zahnung der Scherklinge. Unvermeidliche Reibarbeit des Langhaarscherteils wird auf diese Weise dahin verlagert, wo die Scherarbeit geleistet wird. Dadurch kann die Reibung da geringer gehalten werden, wo es nicht auf ein Andrücken der Scherklinge gegen den Scherkamm ankommt, also an der Klingenrückseite. Aus diesem Grunde wird das Langhaarscherteil leichtgängiger als die vorbekannten Lanchaarscherteile. Weiterhin erhält der Konstrukteur größere Freiheit bei der Gestaltung des Langhaarscherteiles, da die Andrückfedern nicht mehr unmittelbar gegen die Scherklinge drücken müssen. Darüber hinaus kann die Andrückkraft, falls dies erwünscht sein sollte, durch entsprechende Bemessung der Hebelarme des Andrückhebels übersetzt werden, so daß schon mit relativ schwachen Andrückfedern ausreichend hohe Andrückkräfte zu erzielen sind.As mentioned, these pressure forces are directed into the shear blade where it is correct for the function of the long-hair shear part, ie as close as possible to the teeth of the shear blade. In this way, the inevitable rubbing of the long-hair shear part is shifted to where the shearing work is done. The friction since small he be kept where it does not matter to a pressing of the shearing blade against the cutting comb, so on the blade back. For this reason, the long-hair shear part becomes smoother than the previously known lanch hair part. Furthermore, the designer is given greater freedom in the design of the long-hair shear part, since the pressure springs no longer have to press directly against the shaving blade. About that In addition, the pressing force, if this should be desired, can be translated by appropriate dimensioning of the lever arms of the pressing lever, so that sufficiently high pressing forces can be achieved even with relatively weak pressing springs.

Eine vorteilhafte Ausgestaltung der Erfindung besteht darin, daß der Andrückhebel ein einarmiger Hebel ist, der mit einem Ende am Scherkopfrahmen, mit seinem anderen Ende an der Scherklinge anliegt. Durch diese Gestaltung ist die Kräftezerlegung besonders günstig. Die Andrückfedern können unterhalb des Andrückhebels auf einfache Weise in Sacklöchern des Scherkopfrahmens angeordnet werden.An advantageous embodiment of the invention is that the pressure lever is a one-armed lever which rests at one end on the shaving head frame and at the other end on the shaving blade. Due to this design, the breakdown of forces is particularly cheap. The pressure springs can be easily arranged below the pressure lever in blind holes in the shaving head frame.

Vorteilhaft ist es auch, wenn gemäß einer weiteren Ausgestaltung der Erfindung der Andrückhebel mit einem schneideartigen Abschnitt in eine prismatische Ausnehmung des Scherkopfrahmens des Trockenrasierapparates eingesetzt ist. Durch diese Ausgestaltung kann der Andrückhebel mit geringen Reibverlusten die Andrückkraft der Andrückfeder auf die Scherklinge übertragen. Der Hebel ist zugleich in seiner Lage festgehalten, so daß keine besonderen Befestigungsmittel für den Andrückhebel erforderlich sind.It is also advantageous if, according to a further embodiment of the invention, the pressure lever with a cutting-like section is inserted into a prismatic recess in the shaving head frame of the dry shaving apparatus. With this configuration, the pressure lever can transmit the pressure force of the pressure spring to the shear blade with low friction losses. The lever is also held in place so that no special fasteners for the pressure lever are required.

Eine gleichmäßige Andrückkraft über die Breite der Scherklinge erhält man, wenn gemäß einer anderen Ausgestaltung der Erfindung der Andrückhebel gabelförmig ausgebildet ist und dadurch zwei Arme hat, die jeweils sowohl gegen den Scherkopfrahmen als auch gegen die Scherklinge anliegen.A uniform pressing force over the width of the shaving blade is obtained if, according to another embodiment of the invention, the pressing lever is fork-shaped and thus has two arms, which each bear against both the shaving head frame and the shaving blade.

Zweckmäßig ist auch eine andere, vorteilhafte Ausgestaltung der Erfindung, gemäß der jedem Andrückhebel jeweils zwei Andrückfedern zugeordnet sind, welche sich jeweils gegen einen Arm des Andrückhebels abstützen und bei der der beide Arme verbindende Steg torsionsweich ausgebildet ist. Die Andrückkräfte werden durch diese Gestaltung von zwei relativ kleinen Federn erzeugt, welche gut im Scherkopfrahmen unterzubringen sind, und beide Arme können sich unabhängig voneinander an der zugeordneten Scherklinge anlegen.Another advantageous embodiment of the invention is also expedient, according to which each pressure lever is assigned two pressure springs, each of which is supported against an arm of the pressure lever and in which the web connecting the two arms is designed to be torsionally soft. The pressing forces are generated by this design of two relatively small springs, which can be accommodated well in the shaving head frame, and both arms can lie on the associated shaving blade independently of one another.

Eine weitere günstige Ausgestaltung der Erfindung besteht darin, daß die Scherklinge auf der ihrer Verzahnung gegenüberliegenden Seite mit einem schmalen Lappen gegen den Scherkamm anliegt. Durch diese Gestaltung erhält man eine lagensichere Dreipunktabstützung der Scherklinge. Die Gefahr eines Verzugs der Scherklinge durch Schleifen ist gering, weil die vordere Fläche der Scherklinge durch die Verzahnung unterbrochen und als hintere Fläche nur der schmale Lappen zu schleifen ist. Die Anlage der Scherklinge an den Scherkamm ist bei dieser Gestaltung auch dann noch gut, wenn sich die Klinge beim Schleifen geringfügig verwinden sollte.Another advantageous embodiment of the invention consists in that the shear blade abuts against the shear comb on the side opposite its toothing with a narrow rag. With this design, a three-point support of the shear blade is obtained. The risk of warping of the shear blade by grinding is low because the front surface of the shear blade is interrupted by the teeth and only the narrow rag is to be ground as the rear surface. With this design, the contact of the shaving blade to the shaving comb is still good even if the blade should twist slightly during grinding.

Das Problem des Verziehens des Scherkammes beim Schleifen kann gemäß einer anderen Ausgestaltung dadurch gelöst werden, daß der Scherkamm ebenfalls einen schmalen Lappen hat, gegen den der Lappen der Scherklinge anliegt. Aus optischen Gründen ist es bei dieser Ausgestaltung zweckmäßig, eine Abdeckung oberhalb des Scherkammes vorzusehen.According to another embodiment, the problem of warping the shaving comb during grinding can be solved in that the shaving comb also has a narrow tab against which the tab of the cutting blade rests. For optical reasons, it is expedient in this embodiment to provide a cover above the shear comb.

Gemäß einer anderen Ausgestaltung der Erfindung ist der Scherkamm auf seiner seinen Zinken abgewandten Seite verzahnt oder gezinkt. Auch diese Maßnahme dient dazu, ein Verziehen des Scherkammes durch das Schleifen zu verhindern.According to another embodiment of the invention, the shear comb is toothed or pronged on its side facing away from its prongs. This measure also serves to prevent the shaving comb from warping due to the grinding.

The invention allows numerous design options. One of them is shown schematically in the drawing and is described below. Show it
  • FIG. 1 shows a cross section through the shaving head of a dry shaving apparatus with two long-hair shears,
  • FIG. 2 shows a plan view of part of a shear blade of one long-hair shear part shown in the right part of FIG. 1,
  • FIG. 3 shows a view of a pressing lever provided for the long-hair shear part according to the invention,
  • 4 shows a section through the pressure lever according to Figure 3 along the line IV-IV on an enlarged scale.

In Figur 1 ist schematisch ein Scherkopf 1 dargestellt, welcher mittels einer Feder 2 in Anlage an eine Scherfolie 3 gehalten ist. Durch einen Schwinghebel 4 ist der Scherkopf 1 in eine senkrecht zur Ebene der Zeichnung verlaufende hin- und hergehende Bewegung versetzbar.FIG. 1 schematically shows a shaving head 1 which is held in contact with a shaving foil 3 by means of a spring 2. The shaving head 1 can be set into a reciprocating movement perpendicular to the plane of the drawing by means of a rocking lever 4.

Die Scherfolie 3 ist auf übliche, nicht dargestellte Weise innerhalb eines Scherkopfrahmens 5 gehalten. Auf beiden Seiten des Scherkopfrahmens 5 ist jeweils ein Langhaarscherteil 6 und 7 angeordnet. Beide Langhaarscherteile 6 und 7 sind funktionell gleich gestaltet, so daß im folgenden nur das Langhaarscherteil 7 detailliert beschrieben wird.The shaving foil 3 is held in a usual manner, not shown, within a shaving head frame 5. A long-hair shear part 6 and 7 is arranged on each side of the shaving head frame 5. Both long-hair shear parts 6 and 7 are designed functionally the same, so that only the long-hair shear part 7 is described in detail below.

Das Langhaarscherteil 7 hat einen Scherkamm 8, mit Zinken 9, welcher fest mit dem Scherkopfrahmen 5 verbunden ist. Unterhalb des Scherkammes 8 befindet sich eine Scherklinge 10 mit einer Verzahnung 11, welche entsprechend den Zinken 9 gestaltet ist. Ein Andrückhebel 12 liegt einerseits nahe der Verzahnung 11 mit einem Anlageabschnitt 13 gegen die Scherklinge 10, andererseits mit einem schneideartigen Abschnitt 14 in eine prismatische Ausnehmung 15 des Scherkopfrahmens 5 an. Eine Andrückfeder 16, welche sich in einem Sackloch 17 des Scherkopfrahmens 5 befindet, ragt in eine Vertiefung 18 des Andrückhebels 12. Diese Vertiefung 18 ist am Andrückhebel 12 zwischen seinem Anlageabschnitt 13 und dem schneidenartigen Abschnitt 14 vorgesehen. Deshalb wird durch die Kraft P der Andrückfeder 16 der Andrückhebel 12 um seinen schneidenartigen Abschnitt 14 verschwenkt, so daß sein Anlageabschnitt 13 nahe der Verzahnung 11 gegen die Scherklinge 10 drückt. Der Andrückhebel 12 zerlegt dabei die Kräfte der Andrückfeder 16 derart, daß die Andrückkraft in etwa rechtwinklig in die Schneidklinge 10 geleitet wird, was besonders deutlich bei dem in Figur 1 links dargestellten Langhaarscherteil 6 zu erkennen ist, vgl. Wirkungslinien A und B.The long-hair shear part 7 has a shaving comb 8, with prongs 9, which is firmly connected to the shaving head frame 5. Below the shear comb 8 is a shear blade 10 with teeth 11, which is designed in accordance with the prongs 9. A pressure lever 12 lies on the one hand near the toothing 11 with a contact section 13 against the shear blade 10, and on the other hand with a cutting-like section 14 in a prismatic recess 15 of the shaving head frame 5. A pressure spring 16, which is located in a blind hole 17 of the shaving head frame 5, projects into a depression 18 in the pressure lever 12. This depression 18 is provided on the pressure lever 12 between its contact section 13 and the cutting-like section 14. Therefore, by the force P of the pressure spring 16, the pressure lever 12 is pivoted about its cutting-like section 14, so that its contact section 13 presses against the shear blade 10 near the toothing 11. The pressure lever 12 breaks down the forces of the pressure spring 16 in such a way that the pressure force is guided approximately at right angles into the cutting blade 10, which can be seen particularly clearly in the long-hair shear part 6 shown on the left in FIG. 1, cf. Lines of action A and B.

Wie Figur 2 zeigt, hat die Scherklinge 10 einen Lappen 20 auf ihrer der Verzahnung 11 gegenüberliegenden Seite. Dieser ist zum Scherkamm 8 hin hochgezogen und liegt gegen einen entsprechenden Lappen 21 des Scherkammes 8 an.As FIG. 2 shows, the shear blade 10 has a tab 20 on its side opposite the toothing 11. This is pulled up to the shaving comb 8 and bears against a corresponding tab 21 of the shaving comb 8.

Durch diese Gestaltung berühren sich der Scherkamm 8 und die Scherklinge 10 nur im Bereich der Zinken 9 bzw. Verzahnung 11 und mit den Lappen 20 und 21.As a result of this design, the shaving comb 8 and the shaving blade 10 touch only in the area of the prongs 9 or teeth 11 and with the tabs 20 and 21.

Der Scherkamm und die Scherklinge des Langhaarscherteiles 6 sind vorzugsweise ebenfalls mit jeweils einem der Lappen 20 und 21 entsprechenden Lappen versehen, wie dies aus der Zeichnung deutlich erkennbar ist.The shaving comb and the shaving blade of the long-hair shear part 6 are preferably also each provided with one of the tabs 20 and 21 corresponding tabs, as can be clearly seen from the drawing.

Die Fig. 3 und 4 zeigen die Gestaltung des Andrückhebels 12 des Langhaarscherteiles 7. Der Andrückhebel 12 ist gabelförmig gestaltet und hat zwei Arme 23, 24, welche durch einen Verbindungssteg 25 miteinander verbunden sind. Jeder Arm 23, 24 hat den schneidenartigen Abschnitt 14, mit dem er in die Ausnehmung 15 des Scherkopfrahmens 5 greift, und den Andrückabschnitt 13, mit dem er gegen die Scherklinge 10 anliegt. Zwischen diesen Abschnitten 14, 13 ist die Vertiefung 18 in jedem Arm 23, 24 vorgesehen, welche jeweils die Andrückfeder 16 aufnimmt.3 and 4 show the design of the pressure lever 12 of the long hair shear part 7. The pressure lever 12 is fork-shaped and has two arms 23, 24 which are connected to one another by a connecting web 25. Each arm 23, 24 has the cutting-like section 14, with which it engages in the recess 15 of the shaving head frame 5, and the pressing section 13, with which it bears against the shaving blade 10. Between these sections 14, 13, the recess 18 is provided in each arm 23, 24, which receives the pressure spring 16 in each case.

Der Verbindungssteg 25 ist zweckmäßig torsionsweich ausgebildet und erlaubt damit eine unabhängige Anlage der Arme 23 und 24 an der Scherklinge.The connecting web 25 is expediently designed to be torsionally soft and thus allows the arms 23 and 24 to rest independently on the shear blade.
